Abstract
A holder houses a cassette and is arranged to be movable in a horizontal state. A loading mechanism includes a guide for guiding the holder so as to load the cassette from a first position to a second position and to unload the cassette from the second position to the first position, and a driving member for driving the guide in load and unload states. A transmitting mechanism transmits a driving force from a driving source to the driving member. A switch includes a pair of contacts which are turned ON and OFF so as to selectively supply power to the driving source, and first and second actuators for turning ON and OFF the contacts. The second actuator engages with the guide at the second position assumed by the guide so as to turn OFF the contacts. A switching member includes first and second portions which can be freely engaged with the driving member and the first actuator. Engagement of the first portion with the driving member releases at the first position assumed by the guide so as to cause the second portion to be engaged with the first actuator, thereby turning ON the contacts. The first engaging portion engages with the driving member at the first position assumed by the guide so as to cause the second portion to be disengaged from the first actuator, thereby turning ON the contacts.
